Nice quality. Easy to install.
I like that it has a union built in. Was able to cut the old swing type check valve in half and unscrew the two halves and easily spin this one in. No need to get the torch out.

Great for the price
Item came quick and was as described. It also was priced well below what my local plumbing supply charged. Great transaction!
